ILIAS-7-Install-Tutorial for Ubuntu 20.04

Set the Cronjobs in /etc/crontab

Set the Cronjobs

We need 3 cronjobs for ILIAS for the following proposes:
  1. Trigger the ILIAS cronjobs by running it every hour
  2. Trigger the chatserver script - it checks every x minutes, if the service is up and if not, starts it (we already add this)
  3. Trigger the Lucene-RPC-server script - it checks every x minutes, if the service is up and if not, starts it
  4. Run certbot to check for new certificates
  • This will be done by adding 3 lines to the file /etc/crontab: nano /etc/crontab
  • Put the following lines  in that file before the last #:

You can set all ILIAS cronjobs in Administration->General Settings->Cronjobs.
